Location of the reconnection regions in the XY plane when |B_IMF| increases from 10 to 250 nT for Earth–Sun and Sun–Earth IMF orientations. P_d = 1.2 nPa and T_sw = 1.8 × 10⁵ K. The color of the symbols indicates the |B_IMF| value. The stars indicate the reconnection region for the Sun–Earth IMF orientation. The circles indicate the reconnection region for the Earth–Sun IMF orientation.
